CLOCK HAND REMOVER Filed Feb. 20, 1943 Inventor Patented Dec. 25, 1945 UNITED STATES PATENT OFFICE CLOCK HAND REMOVER Elza A. Slagle, Cleveland, Ohio Application February 20, 1943, Serial No. 476,577

1 Claim.

This invention relates to new and useful improvements in implements for use in repairing hands of clocks and watches. 7

The principal object of the present invention is to provide a simple device whereby hands and other mechanical elements of clocks and watches can be pulled in a convenient manner while retaining the mechanical element after it has been removed.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure 1 is a side elevational view of the implement.

Figure 2 is a top plan view.

Figure 3 is an enlarged horizontal sectional view taken substantially on the line 33 of Figure 1.

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 denotes a nut to which a pair of jaws 6, 6 are pivotally secured as at I.

The intermediate portions of the legs of the jaw 6, 6 are formed with openings for receiving the pintle-like ends 8, 9 of an elongated frame l0, these pintles being straddled by the forked free end portions of a U-shaped spring II, the bight portion of which is apertured to receive a screw l2 which is feedable through the nut 5 and which is equipped with a knurled head l3. This screw I2 has a smooth reduced pin extension M which passes downwardly through the frame and is suitably reduced and otherwise formed as denoted by numeral for watch repair work.

The shank 8 of the frame ID has a cross pin Hi to prevent its displacement from the corresponding jaw 6, while the other shank 9 is ,clocks and like mechanisms and more particularly to a device for conveniently removing the threaded to accommodat a knurled nut l1. Obviously, when the nut I! is fed inwardly on the threaded shank 9, the jaws 6, 6 are closed against a clock or watch hand or other mechanical element and against the tension of the spring I I. On the other hand, when the nut I1 is unscrewed the jaws 6, 6 will open in response to the force of the spring ll. Obviously, when the jaws 6, 6 have been clamped against a mechanical element, the screw l2 can be fed inwardly so that the pin 14 engages the shaft or other carrier for the mechanical element by the jaws 6, 6 thus resulting in the pulling oil of the mechanical element from the carrying element.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

An instrument of the character described comprising a nut structure, a pair of pivotal jaws carried by the nut structure, means for expanding and contracting the jaws, and a push member feedable through the nut, said means for expanding and contracting the jaws comprising a frame member for receiving the pushing memher, said frame member being provided with shanks disposed through the jaws, one of said shanks being threaded, a nut on the threaded shank at the outside of the corresponding jaw adapted to be fed against the corresponding jaw to contract the jaws, and a U-shaped spring for expanding the jaws when the nut is unscrewed on the threaded shank, said spring being interposed between said jaws and having a bight portion through which said pusher slidably extends ELZA A.
